Equipment Check

1.1 Follow plant safety regulations prior to equipment disassembly

including, but not limited to, the following:

• Lock out motor and valves.

• Wear designated personal safety equipment.

• Relieve any pressure in the system.

• Consult plant MSDS files for hazardous material regulations.

1.2 Disassemble pump in accordance with equipment manufacturer’s

instructions and remove sealing arrangement.

1.3 Check seal documentation for seal design and materials of construction.

Verify that the ISC2 seal is designed for the equipment being repaired.

1.4 Check seal assembly drawing for any modifications required to the

equipment before installation and act accordingly.

1.5 Check shaft or pump sleeve OD, seal chamber depth, seal chamber

bore, distance to the first obstruction, gland pilot and gland bolting

to ensure they are dimensionally within the tolerances shown on the seal

assembly drawing. Check gland bolt length to ensure adequate thread

engagement for the actual seal gland.

1.6 Thoroughly inspect and clean the seal chamber and shaft or pump

sleeve. Inspect for corrosion or any defects. Remove all burrs, cuts, dents

or defects that might damage gaskets or allow a leak path. Replace worn

shaft or pump sleeve. Remove sharp edges from keyways and threads.

1.7 Check equipment requirements as described in Figure 1. Any reading

greater than what is allowed must be brought within specifications.

The images of parts shown in these instructions may differ visually from the actual

parts due to manufacturing processes that do not affect the part function or quality.
